I have also been running into this on two of our 1.17.1 servers (Paper). On one, we have experienced two crashes caused by this. The first crash was on the 8th of July and the second crash was on the 10th of July. Still seeing the occasional MapLike spam since then but it doesn't seem to be affecting performance too much. The other server doesn't seem to be running into this bug as much but i still see a fair bit of MapLike spam...
